ALFRED REEVES AND JAMES N. l) REEVES, OF COLUMBUS, INDIANA.

STRAW-STACKER.

SPECIFICATION forming part of Letters Patent No. 302,588, dated July 29, 1884-.

Application filed March 3, 1884. (No model.)

To all whom it may concern:

Be it known that we, ALFRED l3. REEVES and JAMES N. D. REEVES, citizens of the United States, residing at Columbus, in the county of extended separately, and a pair of non-extensiblebraees. Said pillar is arranged to turn on a hollow pivot secured to a fixed baseframe, for the purpose of distributing the straw from athlashing-machine over a curved area.

The objects of our improvements are as fol lows: first, to provide a broad base and a low bearing on which the straw-carrier support may turn, thus dispensing with the hollow central pillar and its central hollow pivot, and giving greater stability to the turning support; secondly, to rotate the straw-carrier support and straw carrier by means of mechanism adapted to be connected at will with the mechanism by which the straw-carrier belt is driven; thirdly, to provide means whereby the mechanism for rotating the carrier-support and the straw-carrier, when once connected with the before-mentioned driving mechanism, will antomatically cause the straw-carrier support to continue to rotate alternately in opposite directions until said mechanisms are disconnect ed; fourthly, to provide means whereby the automatic oscillation of the straw-carrier support may be controlled, so as to cause the discharging end of the straw-carrier to move over a long or a short path, as may be desired; iifthly, to provide means for adjusting the height of both ends of the straw carrier simultaneously or separately, as may be desirable; siXthly, to provide means whereby the windlass controlling the receiving end of the strawcarrier may be locked in position before the discharging end of the straw-carrier can be separately adjusted.

The accompanying drawings illustrate our invention.

Figure 1 represents a side elevation; Fig. 2, a section through a, Fig. 1; Fig. 3, a section at line (i, Fig. 4t; Fig. 4, a plan of the mechanism for oscillating the carrier laterally. Fig. 5 is a plan ofthe mechanism for raising the strawcarrier; Fig. 6, a partial. elevation of the same; Fig. 7 a side elevation of the entire stacker.

The construction of our stacker is as follOWS:

A represents the foundationirame, which is designed to be mounted on carrying-wheels. To the upper surface of frame A is rigidly secured an annular cog-wheel, 13, having cogteeth on its outer periphery. Said cog-teeth do not extend the whole depth of wheel B, but are cut short, leaving a space between their lower ends and the planking on frame A.

G is a rectangular frame, forming a turn-ta ble, having friction-rolls a a secured to its under surface, which rolls rest upon the upper side of wheel 13. Turn-table C is movably secured on wheel B, and held concentric therewith bymeaus of clasps b b, which are bolted to said frame, extending downward therefrom an d hooking under the lower ends of the cogs on said wheel. A pair of brackets, c 0, are'secured to opposite ends of a central timber, D, forming part of frame 0. Said brackets form bearings for a horizontal shaft, E, on which is secured a bevel gear-wheel, F, and a sprocketwheel, G. The straw-carrier s c is mounted on two pairs of extensible supports, (1 and e, and a pair of non-extensiblesupportsmx. Said extensible supports are pivoted to opposite ends of the straw-carrier and to the turntable O, and the non-extensible supports are pivoted to shaft E and to the driving-shaft on the strawcarrier, the arrangement and operation being substantially the same as that shown and de scribed in the before-mentioned patent to M. T. and A. B. Reeves. A chain-belt, f, passes over sprocket-wheel G and a similar wheel on the drivingshaft of the straw-carrier, and motion is conveyed to said sprocket-wheel by means of a vertical shaft, 9, located in the center of wheel B, a horizontal shaft, to which the driving-pulley H is secured and bevel gear- Wheels F, h, 'l, and j.

For the purpose of rotating the turntable O by means of the straw-carrier-driving mechanism, a horizontal shaft, k, is mounted in a sliding bearing, Z, and a swinging bearing, on, both secured to the floor of the turn-table 0. Short vertical shafts n 0 are mounted in bearings on the turn-table and carry on their upper ends screw gear-wheels p and g, each adapted to engage a screw, r, on shaft 70, and on their lower ends spur-pinions s and t, both meshing with the cogs on wheel B. Said shafts no are placed alittle farther apart than the diameter of the screw r, so that said screw may revolve without engaging either. Motion is given to shaft is by means of a screw, u, on shaft and a corresponding gear -wheel, 1;, on shaft 7:. Shaft 70 revolves continuously with shaft 9, and when screw r is disengaged from both of gearwheels 19 and q, the turn-table 0 will remain stationary, or may be turned by the operator pushing against the side of the turn-table. By slipping bearing Z toward one of the gear-wheels p or q, screw 0" is engaged with said gear-wheel and the corresponding pinion s or t is revolved thereby turning the turn-table and the strawcarrler. I

For the purpose of automatically turning the turn-table and the straw-carrier alternately in opposite directions, a lever, w, is pivoted at one end to a standard, 00, which is rigidly secured to the turn-table. Said lever 10 is connected with opposite ends of bearing Z by spiral springs y and z, of about equal tension, each secured at one end to the bearing Z and at the other end to lever 10, as shown. Pivoted also to standard :0 are two drop-catches, cc and ca". Said catches are adapted to engage pins pi, projecting from sliding bearing Z,for the purpose of holding the bearing in place when the screw 1' is engaged with either of the gearwheels 1) or q. Said latches are both out of engagement with their respective pins when neither of said gear-wheels is engaged.

I is a wheel, which is pivoted to standard 00. and has pins 1) and p projecting from its side in the path of lever w, and pins p and p arranged to come in contact with the lower edge of catches 0a and ca". Stops st and st are inserted in frame A in the path of lever 10, as the turn-table to which said lever is attached rotates in one or the other direction. The operation of this part of our device is as follows: Screw gear-wheel r, being engaged with gearwheel 1), and shaft is revolving, the turn-table slowly rotates, moving lever 10 toward stop st. The turn-table continues to move forward after the lever comes in contact with the stop, and the lever being detained the tension on spring y is increased and spring 2 released,

the sliding bearing Z, to which the springs are attached, being prevented from moving by the catch ca As the turn-table continues to advance lever w comes into contact with pin 19 in wheel I, and thereby turning said wheel, pin 1) is brought,in contact with the lower side of catch cc and the catch is raised, thus releasing the sliding bearing Z, which, with shaft 75, is then instantly drawn by spring 1 toward gear-wheel q, causing the screw r to intermesh therewith and reversing the movement of the turn-table, which continues to move in the new direction till lever 10 comes in contact with stop st when the direction of movement is again reversed in an exactly similar manner. The proportionate part of acomplete revolution made by the turn-table is governed by the distance between the stops, which may be placed in any one of a series of holes made in the floor of frame A.

It is important to notice here the purpose of catches cc and cc and springs y and z. If

the connection between lever w and bearingZ were rigid, catches cc and ca" could not be used, and when the lever came in contact with the stop the turn-table, moving slowly and having, therefore, but little n1omentum,would. continue to rotate only until bearing Z was moved just far enough to withdraw screw 0' from engagement with its corresponding gearwheel. The turn-table would then stop, there not being movement enough of the bearing Z to carry the screw into engagement with the opposite gear-wheel. This further movement is accomplished by the catch holding the sliding bearing Z until the spring has acquired sufficient tension to draw the screw over into the opposite gearqvheel, when the sliding bearing is released by the raising of the catch, as before explained.

For the purpose of enabling a person on the straw-stack to throw the turntable-rotating mechanism into or out of engagement, cords J and K are attached to wheel I and passed through suitable guides to the discharging end of the straw-carrier, cord J being arranged to turn the wheel in one direction, and cord K arranged to turn it in the opposite direction. For the purpose of operating the extension-supports d and e, and thereby raising the straw-carrier, two windlasses, L and M, are mounted in bearings on the turn-table. Windlass L receives ropes r0 r0, which operate the sliding parts of braces (Z.- The weight of the outer or discharging end of the straw-carrier tends to raise the receiving end, and windlass M and rope re are arranged to draw the sliding parts ofbraces e downward. Vvindlasses L and M are turned by means of a crank,O, and pinion P. Said crank and pinion are rigidly secured to a short shaft, Q, which is arranged to revolve and to slide longitudinally in a bearing, It, on standard S. Pinion P is of sufficient width to engage the gear-wheels of windlasses L and M simultaneously, and is arranged to remain in engagement with windlass L at all times, but is disengaged from windlass M by sliding shaft Q outward, as shown in Fig. 2 in dotted lines.

For the purpose of locking windlass M when pinion P is disengaged therefrom, a dog, It, having one or more teeth adapted to engage the cog-teeth on windlass M, is mounted loosely on shaft Q, being kept in place against pin ion 1? by a pin, 8, through the shaft. Shaft Q is adapted to turn in dog R, but is prevented from sliding longitudinally therein by pin 3.

WVhen pinion P is withdrawn from Windlass WI, dog R is also drawn outward, and the teeth thereon intermesh with those .on Windlass M, and hold said Windlass from turning in either direction, dog B being prevented from turning on shaft Q, by a pin, 5, which projects from the side of the block and engages in the standard S, in which shaft Q and the windlasses have their bearing. With this construction, the act of disengaging the pinion P from windlass M, for the purpose of operating Windlass indepcndently, also looks Windlass M in position. Windlass L is prevented from turning backward by a pawl, '1.
